...In regard to Tesla, yes they have stated that only the 60 and 85kWh packs will have the DC quick charge capability. Not the 40kWh...
This is, IMO, the most bizarre part of the Tesla S marketing plan.
Don't give DC charging, to the shortest range cars, that need it the most?
...
With 60/85 their "Supercharger network" only needs to have DC QC Superchargers ~230 miles apart, not ~160. So less need to build infrastructure. Also, the 40kW is trying to meet a low entry price point, so leaving off any extra hardware is useful towards that goal. But, at the end of the day, the real reason may be that the smaller battery pack may have trouble accepting that much energy so quickly. To go along with the entry cost goal they may consider using a less expensive cell chemistry that is less amenable to quick charging.
So, a $20 k (with tax credit) Mitsubishi has batteries suitable for DC charging, but it would be too expensive to put them in a $50 k Tesla?
Do you believe the 2-ton 60 kWh Tesla S, will go 230 miles on one charge, at freeway speeds?
And that drivers will always find it convenient to stop, exactly where the chargers are?
There has to be redundancy and overlapping range for DC charge stations just as there are for gas stations today.
I Believe the Oregon/Washington network on I-5, is placing DC stations about 30-40 miles apart.
Stations spaced somewhere around 50% of maximum range of the vehicles served, seems about the minimum, to me, for reasonably convenient DC use, by BEV drivers.
BTW, how long will it take to charge the 60/85 Teslas?
Can they charge at the fastest rate, right up to 100%?
